E. coli bacteria are found in nature, such as in the environment, in food, and in the intestines of people and animals. Most E. coli strains are harmless and indeed part of a healthy gut.

But certain strains, such as O157:H7, produce toxins that cause illnesses. Symptoms may include stomach cramps, diarrhea (sometimes bloody), vomiting, and fever, according to the CDC. Most people get better in a week or less, but some people can experience life-threatening conditions such as hemolytic uremic syndrome, a type of kidney failure.
